  • Strictly non-blocking switch core having optimized switching architecture based on reciprocity conditions
    Patent number: 7292747
    Abstract: A switch core is set forth that comprises a plurality of duplex switches that are interconnected with a interconnection fabric to implement, for example, strictly non-blocking operation of the switch core for reciprocal traffic. In one embodiment, an N-way reciprocal switch is implemented. The N-way reciprocal switch comprises a plurality of duplex switches numbering N of at least a 1×(N?1) switch type (e.g., the duplex switches have at least N?1 ports available for connection to implement the interconnection fabric). The interconnection fabric interconnects the plurality of duplex switches so that each duplex switch is connected to every other duplex switch used in the interconnection fabric by a single connection. A similar an architecture using switches numbering N of at least a 1×N switch type are also set forth.
